In May 2005 Invitrogen Corporation (now Thermo Fisher Scientific) acquired Caltag Laboratories and its line of antibodies and reagents for flow cytometry applications. Products formerly offered by Caltag are now part of the Molecular Probes product line.

Molecular Probes has been at the forefront of invention and development of fluorescent probes for nearly 40 years. We have developed an extensive selection of reagents for the flow cytometry–based interrogation of cell structure, function, and dysfunction.

We offer 24 different fluorescent dyes (including the Alexa Fluor family of dyes, and Pacific Blue and Pacific Orange dyes), proteins (PE, PerCP, and APC), and Qdot probes conjugated to a wide range of antibodies to further expand your multiparametric flow cytometry capabilities. This range of dyes is compatible with all flow cytometers.
